FERFORATED PEN HOLDER.

SPECIFICATION forming part of Letters Patent No. 383,185, dated May 22,1888. Application filed October 3], 1887. Serial No. 953,8 .3. (Nomodel.)

To all whom it may concern.-

Be it known that I, FREDERICK llIATTHIAS LII-:BY, of Portland, county ofCumberland, and State of Maine, have invented an Improvement inPen-Holders, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to construct a pen-holder combiningelasticity, strength, and adaptability to receive pens of various sizes,in a new and useful manner.

In the construction of pen-holders heretofore no attempt has been madeto give elasticity to the holders themselves other than by making themof material more or less elastic or providing an independent barrel ofmetal slitted longitudinally, the main reliance being placed on the pento be used. Many pens now constructed havelittle pliability, therebycansin g much discomfort by their use for any length of time inconnection with ordinary holders; and it is the purpose of this myinvention to provide a penholder that may be used with any pen, hard orsoft, without tiring the hand during long continuous use and withoutsacrificing unduly the strength of the holder.

My invention consists, essentially, of a penholder slitted transversely,whereby elasticity .is imparted to the said holder.

Figure 1 is a top view of a pen-holder em bodying my invention; Fig. 2,asection of Fig. 1, taken on the linear or; and Fig. 3 is an enlargedcross-section of Fig. 1 on the line y y.

The holder (1, of rubber, zylonite, celluloid, horn,wood, or othersuitable material, is preferably hollowed out for a portion of itslength, as at I), (see Fig. 2,) and has fitted therein a plug, 0,provided with aslit, d, to form jawsee.

The plug 0 is corrugated, preferably longitudinally, for a part or thewhole of its length, as at f, (see Figs. 2 and 8,) the said corrugationsenabling a pen to be more firmly held when inserted between the holder aand the slitted end of the plug, the slit (Z allowing the jaws c c to bepressed toward each other to accommodate pens of various sizes andcurvatures.

\Vhen the plug is constructed as above, the best results are attained;but itis obvious that the exact form of plug may be changed with" outdeparting from my invention.

It is also obvious that a separate plug may be dispensed with altogetherby making the holder a in two parts, hollowing out one end of one of theparts and making at its other end a recess to receive the pen, and thenuniting the two parts of the holder in any suitable manner.

At or near the back of the plug 0, or its equivalent, as described, theholder a is provided with one or more series (preferably two) oftransverse slits or saw-cuts, as at as, (see Figs. 1 and 2,) the saidslits being substantially parallel to each otherand of equal length.Vhen the material of the holder is such that the slits would tend tosplit or, splinter it, a double row of holes, as at t, (best shown inFig. 1,) may be bored and then the slits or saw-cuts made, terminatingat each end in one of the holes. A single series of slits will besuflicient to give the requisite elasticity to the holder; butIpreferably make two such series diametri' cally opposite each other, thebest results being accomplished by this latter construction.

Owing to the position ol'the transverse sl1ts viz., at or near thebackof theplug-the holder is rendered elastic at that portion grasped by thefingers ofthe writer and in an up-anddown direction, and lateralflexibility is prevented by the uuslitted longitudinal portion of theholder contiguous to the series of slits, it being desirable to have theholder somewhat stilf laterally.

Hereinbefore and in the claims in speaking of the slits or saw-cuts Ihave used the term transverse slits, and by such term I mean slits orcuts in the holder at right angles, or nearly so, relative to thelongitudinal axis of the said holder.

I do not desire to limit myself to the exact form of pen-holder hereinshown and. described to any particular form or number of slits or cuts,nor to the exact position of the same relative to the longitudinal axisof the holder, as I believe myself to be the first to construct apen-holder homogeneousthroughout and made elastic by reason of a seriesof short independent transverse slits or cuts.

I claim- 1. As an improved article of manufacture, a pen-holder ofhomogeneous material and slitted transversely for a small portion of thelength, whereby elasticity is imparted to the said penholder at suchportion, substantially as de scribed.

2. As an improved article of manufacture, a homogeneous pen holder madehollow for a portion of its length and provided with a series of shortand disconnected transverse sawcuts in the said hollow portion near itsouter end, substantially as described.

3. As an improved article of manufacture, a homogeneous pen-holder madehollow for a portion of its length and provided with short transverseslits, combined with a longitudi nally-slitted plug to fit into theouter end of the said hollow portion, substantially as and for thepurpose set forth.

4. As animproved article of manufacture, a homogeneous pen holder madehollow for a portion of its length and provided with independenttransverse slits, combined with a corrugated or milled cylindrical plugto fit into 2c the outer end of said hollow portion, substantially asand for the purpose set forth.

In testimony whereof I havesigned my name to this specification in thepresence of two subscribing witnesses.
